Abstract

The invention relates to the technical field of hydraulic devices, in particular to a dust-proofing hydraulic cylinder comprising a cylinder body, a piston, a piston rod, a cylinder cover and an oil inlet. The piston is placed in the cylinder body and is fixedly connected with the piston rod, the oil inlet is formed in the cylinder body and is communicated with the cylinder cavity, and the piston rod is sleeved with a dust removing sleeve. The dust removing sleeve is arranged on the piston rod and is in a three-segment structure, a piled fabric ring is used for intercepting large-particle dust firstly, a rubber ring is used for intercepting small-particle dust, a silicone ring is used for final cleaning so that the cylinder oil cavity is insulated and hermetically isolated from the outside, water proofing, dust proofing and corrosion proofing can be achieved, normal operation of the cylinder can be guaranteed effectively, and service life is prolonged.

Description

Anti-gray hydraulic jack
Technical field
The present invention relates to hydraulic pressure installation technical field, especially a kind of anti-gray hydraulic jack.
Background technique
As a kind of conventional mechanical component, hydraulic jack is widely used at mechanical field, existing hydraulic jack is all provided with dust ring and is used for stopping extraneous dust, but in the long-term to-and-fro motion of piston rod, not only piston rod long term exposure outside, subject to damage, dust ring also can become flexible distortion, easily make dust, sewage enter cylinder body, affect performance, reduction of service life.
Summary of the invention
In order to overcome the deficiency of existing hydraulic jack easy damaged, dustproof and waterproof weak effect, the invention provides a kind of anti-gray hydraulic jack.
The technical solution adopted for the present invention to solve the technical problems is: a kind of anti-gray hydraulic jack, comprise cylinder body, piston, piston rod, cylinder cap and pouring orifice, piston is placed in cylinder body and is fixedly connected with piston rod, and pouring orifice is positioned on cylinder body, be communicated with inner chamber of cylinder block, upper cover of piston rod has dust removing tube.
According to another embodiment of the invention, further comprise that dust removing tube is three-stage structure, front end is Villus cloth circle, and stage casing is rubber ring, and rear end is silica gel ring.
The invention has the beneficial effects as follows; one dust removing tube is set on piston rod, and dust removing tube is three-stage structure, and Villus cloth circle is first tackled large particle dust; rubber ring stops fine dust; silica gel ring is done last cleaning, and three steps are a chain of, stepped combination dedusting; thereby thoroughly cylinder body oil pocket is isolated from the outside to sealing; waterproof and dustproof, corrosion protection, effectively ensured the normal operation of oil cylinder, extended working life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. cylinder bodies in figure, 2. piston, 3. piston rod, 4. cylinder cap, 5. pouring orifice, 6. dust removing tube, 61. Villus cloth circles, 62. rubber rings, 63. silica gel rings.
Embodiment
If Fig. 1 is structural representation of the present invention, a kind of anti-gray hydraulic jack, comprises cylinder body 1, piston 2, piston rod 3, cylinder cap 4 and pouring orifice 5, piston 2 is placed in cylinder body 1 and is fixedly connected with piston rod 3, pouring orifice 5 is positioned on cylinder body 1, is communicated with cylinder body 1 inner chamber, and on piston rod 3, cover has dust removing tube 6.Dust removing tube 6 is three-stage structure, and front end is Villus cloth circle 61, and stage casing is rubber ring 62, and rear end is silica gel ring 63.
One dust removing tube 6 is set on piston rod 3; dust removing tube 6 is three-stage structure; the Villus cloth circle 61 of front end is first tackled large particle dust, and the rubber ring 62 in stage casing stops fine dust, and the silica gel ring 63 of rear end is done last cleaning; three steps are a chain of; stepped combination dedusting, thus thoroughly the oil pocket of cylinder body 1 is isolated from the outside to sealing, waterproof and dustproof, corrosion protection; effectively ensure the normal operation of oil cylinder, extended working life.
